Vitamin C serums can be expensive and I've recently found a cheap alternative.
REDERMIC C From La Roche Posay claims to have 5% ascorbic acid concentration. However it contains water, and I've read on your blog that creams with water should be especially formulated to preserve Vitamin C properties.
Could you please look at the ingredient list and assess whether this product is going to be effective?
